There certainly is hope. My husband and I were each in for well over 50 years.
We were both in the full time work, husband in bethel etc. We are fading for doctrinal reasons.
Do not give up hope. Someone said about you showing them love even though they don't.
Wonderful, love is the most effective. They can't tell you how they are aching inside because they have to shun you. t wouldn't be loyal to Jehovah, they think. But it is tearing your mother apart. It is by far your best weapon. Use it to the full.
